To all whom it may concern.'

Be it known that l, CHARLES D. Sinin', a

citizen ot the United States, and a resident of Rockaway Park, in the county of Queens and State of New York, have invented a certain new :1nd useful Vaporizer or Curbureter for (ins-Engines.

My intention relates to improvements in raporizers or Corbin-eters in which a vulve or cock at the carburetor is controlled by an adjusting rod with wheel. The idjusting` rod in conjunction with u specially arranged electric switch, also establishes und disrupts the electric spin-king circuit :is desired; und the objects of my invention are, first, to provide un accessible menus of opening the cock and nt the sume time establishing the electric sparking circuit: second, when ciosing the cock to disrupt the electric sparking circuit; third, to adjust the partial closingl ot' the cock, therebyY regulating the flow of gzisolene or liquid fuel entering'l the curbureter without disrupt-ing the electric sparking iircuit. I nttz'iiu these objects by the mechanism illustrated intheztcr-onipnnying drawings. in which Figure l, is a; rerticnl .section of thc vaporizer or cnrbureter and shows the cock with swivel stud, adjusting,r rod with hund wheel and locking spring switch with binding posts; Fig. 2, is :t bottom view of the. curlmreter: Fig. 8, is :t vertical view ot n pnrtl)r hollowA plug contnining' :i screen und bushing; Fig. al, is n sectional View of a.

In Fig. i, Z is n lever cock. The gnsolene l i l l l l l l l l i t l l i i l l i l i i l l i i i l l l i l l or iiquid fuel enters this cock and passe: through the pipe Y and tiows into the chiunber T. ln this chamber T, inserted :i partly hollow plug K, with n Screw thread, and Ground n part ot' the plug,r K, is platee-cl a screen for screening the gnsolenc or liquid t'uel. ln the top of the ping K isserewed n bushing L, (see Figs. l and 3). The bushing L, hos a hole in the center of it, the size ot' which is determined by the maximum tlow of gnsolene or liquid fuel required for n specific size ot' engine. lhe gnsoiene or liquid fuel after entering the chiunber T, passes through the screen 5 and the holes K', into the hollow part of the plug:r K und from there itis sucked by the engine or forced by the pressure of the gesolcne or liquid fuel behind it, through the bushing L, into the tube D, where its tiow is in 1 measure arrested by the ball valve or sprayer A. The litt of the bull vulve or sprayer A, is caused by suction from the engine and the pressure oi" the gusolene orliquid fuel undef.` it. und is regulated by the eccentric cuni ll in the center of the Snnft E (Fig. 4). The shaft E andthe corn H,'

nrc turnedby the milled nut l, which is held in any fixed position desired, by the. ball spring O.

u u. are n number of :tir ports extending from the bottoni of the vatporizer or cnrbureter, (see Fig. 2) up to the mixing chzin1- bei' X. These ports site for the purposes of e furnishing the tixcd nir supply white others ri a. und n; a; are used for the auxiliar)Y air supply :ind a a :irc tapped and threaded where they enter the mixing chznnber X und into them :irc inserted smul] tubes threaded at, the bottom 1(1', (see liig. 5). These tubes, u' u', :1re tlnred und open :it the top :ind :ire covered b v cups of, with holes in them a, from which the fiuxilinry nir issues. These caps :are crimped nt. the bottom to prevent'- their coming otll the tlnred tubes a a', (see 11`ig'. 5i). Between the cups aF' :uid the bottoni of the mixinpr chnniber X, ore springs rf', voili-cl :round the tubes n; und when the buttertlj.' rzllre N is open or mrtly open, the springs u, :ind the stu-tion iront the engine through C, raise the t-:ips a.: on the open end tubes a', so that nir cnn be sucked through the holes a4 :uut when the buttertly 'nlretiil is closed or partly closed, it pushes down the caps a2, on the. open end tubes a', so that .fi less volume or no ai: cnn be sucked through the holes o* in the cups a`. The butterfly valve N, is operated by the shaft Z2 and the lever P (Fig. l). The gasolene or liquid fuel after being mixed with air in the mixing chamber X: passes out ot' the vaporizer or carbureter at C.

The bottoni of the vaporizer or carbureter is threaded at R. to receive a union with bentpipe connection G G', which may be connected to heated air and both the tixed' air ports a and the auxiliary air tubes f", thus be supplied with heated air; o: te openings leading to the auxiliary air tubes a may be plugged at the bottom of the vaporizer or carbureter and tubes run through the side of the vaporizer or carbureter a5 a5 Fig. l, connecting with the tubes a and the vaporizer or carbureter thus be supplied with cold auxiliary air, while the ports a, are supplied with heated air; or vice versa.

In Fin'. l, the cock Z2 with the lever U, is in a ully open position at 45. In the end 62 the lever U is a swivel stud M, (Figs. l and 7), the small part of which passes through a hole in the lever U and is held in place by a pin through M2, permitting the swivel stud M to turn readily. .ln the head of the swivel stud M, is a threaded hole M', into which screws the threaded end of the adjusting rod V (Figs. l and 7). The adjusting rod V passes through a support J, which in case of an automobile is generally the dash-board. The adjusting rod V then asses through a hole Q5 of an insulated iilock Q (Figs. l and 6), which is attached to the support J. Into this block Q, are'V inserted in each side, metal pieces Qn Q" which hold the binding posts Q Q with nuts and also hold in position the contact springs Q3 Q3 which are coiled around the conical pointed contacts Qt. Q4. The points of these contacts project for a short distance into the large hole Q5 in the insulated block Q. `Where dry cells lV Fig. 8 or storage batteries are used as a source of electrical energy for sparking purposes Figs. l and 8 the binding posts Q Q are connected by wires lV to the electrical circuit Fig. 8 (preferably the ground side). The adjusting rod V is insulated for a portion of its length V2 (Fig. l). It also has a grooved metal contact V which is placed over the insulation V2. It is obvious that, with a rod V of the proper length, when the grooved metal contact V is in Contact. with or between the contact points Q* (y, the cock Z, which opens at 45, will be open and the gasolene or liquid fuel will flow into the carbureter and the electric sparking circuit will be established. It is also obvious-that Whenethe grooved metal contact V of the adjusting rod V, is pushed out of contact Wit-h the contact points Q* Q4, far enough to close the cock Z, the flow of gasolene or liquid fuel willbe cut ott` and the insulated portion V2- of the adjusting rod V. will be lrerwoen the contacts Q* Q* and the electric sparking circuit vrill'be disrupted.

ld/'hen the cock Z is opened by the adjusting rod V. being pulled into the position of contact between its grooved metal contact V' and the contacts QL Qt, the points of these contacls iii, into the grooved portion of V and the springs Q3 Q3 around the contacts Q* Qt, will press their points against th,J grooved metal contact V of the adjusting rod V, thereby holding it in such a position, that by turning the hand wheel V3, the thread on the end of the adjusting rod V, will engage with the. thread in thc swivel stud M in the lever U of the cock Z and partly close the cock Z, thus regulating the tiow of the gasolenc entering the carbureter, While maintaining the electric sparking circuit without interruption.

Some forms of magnetos W2 9, used as a source of energy for electric sparking, require' that the switch to stop them, shall shortcircuitthe armature current of the magneto F ig. 9. there such magnetos are used, the Wires lV from the binding posts ,Q Q are cut into the magneto circuit Fig. 9. In such cases the adjusting rod V.I instead of having a grooved metal contact V. would.

require this art to bc in insulated groove and the insu ated part/V2 of the adjusting rod V, would be made of metal, so that when the cock Z was open,- this insulated groove would be between the contact points Q* Q4 and the magneto would continue in operation, and when the cock Z Was closed Fig. 9 by pushing the adjusting rod V out of the insulated groove. the metal part of the adjusting rod V. would make a contact with the contact points Q4, Q", thus short circuiting the armature current and stopping tte magneto. It is therefore obvious that the adjusting rod V can be constructed for either batteries or magnetos used as a source of energy for electric sparking of gas engines.

This vaporizer or carbureter can be made in several ways; but I prefer to carry out this feature of my invention as shown in the drawings.
